The title compound crystallizes with an alluaudite-like structure. All atoms of the structure are in general positions except for four, which reside on special positions of the space group, <jats:italic>C<\/jats:italic>2\/<jats:italic>c<\/jats:italic>. The Ag<jats:sup>+<\/jats:sup> cations reside at full occupancy on inversion centre sites and at partial occupancy (64%) on a twofold rotation axis. In this structure, the unique Fe<jats:sup>3+<\/jats:sup> ion with one of the two Zn<jats:sup>2+<\/jats:sup> cations are substitutionally disordered on the same general position (Wyckoff site <jats:italic>8f<\/jats:italic>), with a respective ratio of 0.68\/0.32 (occupancies were fixed so as to ensure electrical neutrality for the whole structure). The remaining O and P atoms are located in general positions. The three-dimensional framework of this structure consists of kinked chains of edge-sharing octahedra stacked parallel to [10\\overline{1}]. These chains are built up by a succession of [<jats:italic>M<\/jats:italic>O<jats:sub>6<\/jats:sub>] (<jats:italic>M<\/jats:italic> = Zn\/Fe or Zn) units. Adjacent chains are connected by the PO<jats:sub>4<\/jats:sub> anions, forming sheets oriented perpendicular to [010]. These interconnected sheets generate two types of channels parallel to the <jats:italic>c<\/jats:italic> axis, in which the Ag<jats:sup>+<\/jats:sup> cations are located.
